42131526 ÷ 106 
The aim is to understand the frequency of 106 in 42131526.

On to step 1:
When dividing 4 by 106, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 106

Advancing to step 2:
106 goes into 42 0 times with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 106

On to step 3:
When dividing 421 by 106, we get 3 with a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 318 from 421 and we're left with 103.
Include the next digit (3) from the dividend after 103, then repeat: 1033 / 106

Going ahead to step 4:
106 goes into 1033 9 times with a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Deduct 954 from 1033 and we're left with 79.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 106

Going ahead to step 5:
791 divided by 106 is 7 with a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
If we take 742 away from 791, we end up with 49.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 106

Moving on to step 6:
When dividing 495 by 106, we get 4 with a remainder of 71.
Put 4 as the next digit of the answer. 
Result so far: 3974.0
If we take 424 away from 495, we end up with 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 106

Going ahead to step 7:
If we divide 712 by 106, we get 6 and a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 39746.0
If we subtract 636 from 712, we get 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 106

Going ahead to step 8:
106 goes into 766 7 times with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 397467.0
If we subtract 742 from 766, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
When dividing 240 by 106, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 397467.2
Subtracting 212 from 240 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
106 can be fit into 280 2 times, resulting in a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 397467.22
The remainder is 68 after subtracting 212 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 397467.22 and a remainder of 0.068.
